Abstract: 1,105,451. Fluid-pressure servomotor systems. SPERRY RAND Ltd. July 1, 1964 [July 5, 1963], No. 26703/63. Heading G3P. [Also in Division F1 A spool valve for controlling a reversible  hydraulic motor comprises a spool 16 having a  threaded portion 18 which co-operates with a nut 23. The spool 16 is connected to a cam 20 which co-operates with a roller 22. The nut 23 is loaded by a spring 25 to engage the cam and is connected to the valve sleeve 5 through a tongue and slot mechanism 24 whereby the nut can be rotated by rotation of the sleeve 5. In operation, the spool is rotated by a drive to a shaft 6 and the spool is moved axially through the threaded portion 18 and the cam 21, acting through the nut, to control the supply to the motor. Rotation of the motor acts through gearing (not shown) to rotate the sleeve 5 and nut 23 to cause movement of the spool in a direction opposite to the movement caused by rotation of the shaft 6. The arrangement provides a non-uniform rotation of the hydraulic motor for uniform rotation of the shaft 6. The shaft may be rotated by a pilot or auto-pilot and the hydraulic motor actuates aircraft control surfaces. The shaft 6 may be rotated by an electric motor and the hydraulic motor drives the rollers of a textile combing machine. In a modification, the cam is outside the housing and acts through levers.

Title: Improved process and apparatus for pulverizing or fine grinding
IPC: B02C13/00
Filed: 1919-11-07
Abstract: 159,925. Seymour, F. Nov. 7, 1919. Impact pulverizers.-In a process and apparatus for pulverizing or fine grinding by means of beaters mounted on discs rotating rapidly in coaxial chambers separated by peripheral diaphragms having axial openings for the passage of air and the material being pulverized, a flow of air and solid material is produced longitudinally through the chambers and the material is subjected to successive transverse selective pulverizing actions in a tubular air current therein, the shell of the tubular air current being relatively thick and substantially unobstructed towards the beginning of the pulverizing operation and thin and longitudinally undulating towards the end of the pulverizing action. The machine may have pulverizing-chambers 3 - - 6, Fig. 1, of progressively larger diameter, the openings 9, 10, 11, 12 of the diaphragms being all of the same or nearly the same diameter while the disc 18 in the first chamber 3 is relatively small, leaving a wide margin between it and the diaphragm opening out of that chamber, and the discs 18 - - 21 being progressively larger until in the last chamber 6 the disc 21 is as large or nearly as large as or larger than the diaphragm openings into and out of that chamber. Or, as shown in Fig. 2, the pulverizing-chambers 3 - - 6 may be of the same diameter, the discs 18, 19, 20, 21 being of about the same diameter and the outlet opening of the diaphragm 9 in the first chamber 3 large so as to leave a wide margin between the opening and the disc 18, while the diaphragm openings are progressively smaller until they are about the sama size as the discs. In either case, the margin between the discs and the diaphragm opening is relatively large in the first chamber and progressively less towards the last chamber, so that the shell of the air tube becomes thinner and thinner with more pronounced radial bends. The corrugated paddles or beaters 22 are carried on rigid or swinging arms extending from the discs, which are secured by shearing-bolts 24 to hubs 23 on the shaft 14. Retaining-rings 25 secured bv screws 26 hold the discs on the hubs after the bolts 24 have sheared due to an obstruction entering the machine. The paddles may be bolted to angle-iron palms 28 riveted to the ends oi the arms, or formed with rear or edge lugs through which securing-bolts pass. Or the paddles may be secured directly to the discs. A fan chamber 8 and an auxiliary air-chamber provided with air inlets 32 fitted with dampers 33 are provided at the discharge end of the machine. The pulverizing and fan chambers are lined with plate linings 30 bolted or riveted to the shell 2. The coal &c. to be pulverized is fed through a shoot 34 from a feeding-device.

Title: Improvements relating to protective systems for electrically driven pumps
IPC: F04D15/02
Filed: 1954-09-23
Abstract: 752,305. Controllers; fluid actuation of switches. TAFEL, J. Sept. 23, 1954, No. 27525/54. Classes 38(3) and 38(5) An electric motor M drives a pump U and is connected to an overload-undervoltage circuit-breaker N controlled by a pressure or float-operated switch C which causes stopping or starting of the pump motor when the delivery pressure of the pump reaches a high or low limiting value. In addition, the system is provided with a protective switch W which is adapted to disconnect the pump motor where there is a lack of water in the pump, due to an airlock, for example. The switch W is adapted to close at a pressure slightly below that at which the switch C opens, and to open at a pressure slightly below that at which the switch C closes, so that a drop in pressure below the normal allowable limit due to a fault in the hydraulic system causes the switch W to disconnect the pump motor. For starting the pump, the switch W, or both the switches C and W, are shunted by a manual switch W. The switch W comprises a contact A carried on a tiltable lever Y to which is applied a force dependent upon the fluid pressure exerted by the pump. The cooperating contact B is supported on a stud G, the tension of spring Z determining the upper limit of pressure at which the switch operates, and the position of nut D fixing the lower limit. In a modification, the switch W is connected directly in the three-phase supply leads to the motor, in series with the switch N. In this case, the contacts A and B control a solenoidoperated switch. The protective switch may operate an alarm signal.

Abstract: 1,083,295. Feeding sheets. A. MALAMOOD, and H. MALAMOOD. June 30, 1965, No. 27651/65. Heading B6B. Successive batches of sheets 27 of relatively flexible, thin paper are fed along a feed table, which is tilted, by an endless conveyer comprising a pair of chains 41 provided with a series of pairs of feed lugs, such as 70, and a side gauge 23 at the lower edge of the table, and towards which the sheets fall under gravity, registers the moving batches. The batches 27 are fed intermittently by the chain lugs along a straight, horizontal paper line P from a deposit section 38 to a machine 21 which punches &c. the sheets when the latter are fully registered, and then to a section 39 where they are deposited in a hopper 142. When the batches 27 approach the machine 21, their upper edges are urged against the back gauge 23 by an angled deflector plate 102, Fig. 2 (not shown), and a pair of flexible, resilient metal strips, such as 104, press lightly on the top of each batch to hold it against the pairs of feed lugs 70. Further, when the batch 27 is at rest within the machine 21, a jogger 111 engages the front end of the batch to urge it into contact with the feed lugs 70. The exact positioning of the chain lugs 70 during a sheet-working operation is ensured by a cam-operated latch means 91, Fig. 6 (not shown), having a stop portion 97 which cooperates with an abutment 96 on a drive shaft 77 in the chain drive. The two chains 41 are mounted on sprockets which can be adjusted along cross-shafts, and one such shaft 54 is connected by a chain 75 to the shaft 77. The shaft 77 is rotated intermittently and unidirectionally by a ratchet pinion from a rack 81 which is oscillated by a motor-driven crank. Feed rollers 146, 148 assist the deposition of each batch 27 into the hopper 142. The punching &c. machine 21 is operated by tripping a solenoid 26, Fig. 6 (not shown), but the machine will not operate until a switch 137 has been closed by a cam 138 on the chain drive shaft 83, and a switch 139 has been closed by an arm 141 which senses the presence of a batch 27 of sheets in the machine.
